Nano ID Generator

Quickly and easily generate random Nano IDs with this Nano ID generator.

Nano ID is a modern, tiny, and secure library for generating unique strings. It is a popular alternative to UUID and is commonly used in modern web applications.

What does a generated Nano ID look like?

By default, a Nano ID consists of 21 characters from a URL-safe alphabet (A-Za-z0-9_-). You can customize the length of the generated ID depending on your use case.

Advantages of Nano ID

Nano ID is a minimal library that generates IDs faster than UUID.

URL-safe

The generated IDs only use characters that are safe to use in URLs without encoding.

Customizable length

Unlike UUID, you can easily choose how long your identifier should be.

Cryptographically secure

Nano ID uses cryptographically secure random number generators.
